SCENARIO

SUMMARY

Current plant operating status:

The plant is operating at 87% power.

Scenario segments:

Raising RR flow to increase reactor power. This is the reactivity event for the RO. When the ILT Examiner is satisfied, then the scenario can continue.

ARPM Downscale Failure. The C APRM will fail downscale. The RO will follow ARP actions, while the CRS will address Technical Specifications.

Respond to an inadvertently locked-up Feed Reg Valve by resetting it in accordance with ARP 1C05A, F-1.

While the operators are involved with resetting the Feed Regulating Valve lockup, the main condenser will develop a slow air leak. The loss of vacuum will be at a rate that allows them to work through the AOP for Rising Condenser Backpressure (AOP 691) and the ARPs for HI BACK PRESSURE (1C07B, D-9, 1C07B, B-1, and 1C07B, C-1). The condenser backpressure will be degrading for 14 minutes without audible alarm. The Offgas high flow will come in at ~14 minutes.

Step 3 of AOP 691 will direct the crew to perform a Fast Power Reduction per IPOI 4 Section 6.0. The fast power reduction will place the plant above the MELLA line, requiring entry into AOP 255.2.

As the condenser back pressure continues to increase, it will approach 7.5" Hg abs.,

forcing the operators to insert a Manual Scram and perform IPOI 5 actions. The manual scram will also cause them to enter into EOP 1 on low RPV water level. Once the crew scrams, main condenser vacuum improves due to the reduction of heat load.

Following the reactor scram a steam leak will develop in the Steam Tunnel. The MSIVs will fail to auto isolate the leak, and will require the crew to manually shut the MSIVs.

Rev. 0 2008 NRC Scenario #1 SCENARIO TIME-LINE TIME/NOTES INSTRUCTOR ACTIVITY EXPECTED STUDENT RESPONSE Event 3 Feed Reg Valve Lockup On prompting of the Examiner, insert the Event Trigger to start Event 4. This event takes ~15 minutes before the first alarm (although the crew may notice the vacuum loss prior to that)

Begin the transient by toggling Activate ET 3 to TRUE Role play as NSPEO sent to check the A Feed Reg Valve:

Found a WCC operator hanging a Section Tag on V30-572 (air to A Feed Reg Valve) rather than on V30-972 for CV-6334.

Rev. 0 2008 NRC Scenario #1 SCENARIO TIME-LINE TIME/NOTES INSTRUCTOR ACTIVITY EXPECTED STUDENT RESPONSE Event 4 Condenser Air In-Leakage Booth Instructor:

Activate ET 4 This will begin the condenser air inleakage on a ramp of 60 seconds to 0.6. This will begin a very slow backpressure rise. It takes approximately 14 minutes to reach the first alarm (OG Trouble, due to SJAE high flow). With no operator action, the 5 backpressure alarms will come in 23 minutes later. This slow degradation of vacuum allows the crew to use AOP 691.

NOTE: When the crew performs a fast power reduction per IPOI 4, the backpressure starts to go down again.

Booth Instructor:

WHEN the crew performs Fast Power Reduction (OR at the discretion of the Examiner):

Change MC04A to 0.8 with NO RAMP This increase the backpressure degradation.

Role Play:

If sent to change the SJAE lineups, report back in 30 minutes that you have completed the action that they directed since these actions would be transparent to the control room operators.

If sent to look for the vacuum leak, report back in 30 minutes that you cannot find the leak.

BOP Respond to annunciator 1C07A, D10 OFFGAS PANEL 1C-34 TROUBLE.

SCENARIO

SUMMARY

Current plant operating status:

The plant is operating at Full power. HPCI is tagged out due to failing the Quarterly Surveillance (it did not come up to rated speed in time.) LCO day 2 of 14.

Scenario segments:

STP 3.3.1.1-21, Manual Scram Functional Test will be run on Channel A3. This channel will be successful.

STP 3.3.1.1-21, Manual Scram Functional Test will be run on Channel B3. This channel will fail this test. This will result in a Technical Specification entry. TS 3.3.1.1 Condition A.

The B GSW pump trips and the A GSW fails to auto start. The pump will start when the operator starts it manually (step one of AOP 411 LOSS OF GSW, immediate actions)

The CRS will receive a phone call from the SBDG System Engineer. The SE will inform the CRS that the B SBDG contains a main circuit board in its voltage regulator, and the vendor has contacted us and informed us that the circuit board is faulty, and cannot be counted on to work properly. The A SBDG is NOT effected by this problem. This will result in the B SBDG being declared INOP.

A LOCA will develop in the Drywell. This will result in the reactor being scrammed, and entry into EOP-1 and EOP-2.

Due to the LOCA, the DW will heat up to the point that requires DW spray to be implemented. Initiating DW sprays before 280°F is a Critical Task.

After the DW sprays are initiated, a loss of all high pressure feedwater will occur (RCIC stays running, but will be unable to maintain level), which, in conjunction with the LOCA, will force the CRS to enter the ALC leg of EOP-1, and eventually direct an Emergency Depressurization due to low level. The ALC ED being performed before -25 is a Critical Task.
